LOADED SHOT CARTRIDGE.

Application filed July 17, 1922. Serial No. 575,552.l

To all whom t may concern:

Be it known that I, CHARLES Ln ROY HOLDEN, a citizen of the United States, residing at Kings Mills in the county of Varren and State of hio, have invented certain new and useful Improvements in Loaded Shot Cartridges7 Vof which the following is a specification. My invention relates to loaded shotcar tridges and has for one of its objects the provision of a device of this character which will give improved distribution of shot and cover long ranges.

A further object is the provision of a loaded shot cartridge in which there is means for preventing the exploded powder charge from coming in contact with the shot charge.

A still further object is the provision of means for providing a member which will have a gas-tight connection with the firearm in which the cartridge is exploded between the shot and powder charges.

Other objects will appear hereinafter.

An embodiment of my invention. is illustrated in the accompanying drawing forming a part of this specification and in which- Fig. A is a central sectional view of a 30 loaded cartridge embodying my invention;

Fig. B is a bottom view of the same;

Fig. C isa side view of a member used in the construction; and Y F ig. D is a bottom view of the cup member shown in Fig. C.

Referring more'particularly to the drawing, I have indicated a tubular container l for enclosing a shot charge 2. The member l is preferably closed at` its outer or'upper end, as viewed in F ig. A. This closed end may be semi-spherical, as indicated, or have any other desired configurations. The bottom end of the container l may be closed by a wad 2 of ordinary or any preferred construction. The container l may be formed of Vany desirable substance, either metallic or non-metallic, which will hold the shotY in place while being propelled through the barrel vof the firearm and prevent the shot from coming in contact with the barrel of said rearm. This has ,a particular advantage in preventing the shot from sticking to the gun barrel or leading the latter. i A cup member 3 has its bottom disposed against the lower open end of container l with the walls of said cup extending downwardly partially over a powder charge l which is disposed in the bottom of a shell or cartridge 6. The cup 3 has its side walls 3 of yieldable material so that when the' cartridge is used the wall 3 of the cup will expand out against the barrel of the firearm and prevent the explosive gases from passino' by said cup. This cup therefore provi es a sealing means and also provides a means for preventing the excessive heatof the exploded gases from melting or injuring the shot adjacent saidy said cup. The wall 3 of the cup is preferably thinner at the open side of the cup than adjacent the bottom, as clearly indicated by dotted lines in Fig. C. This construction helps the wall 3 to be expanded easily Yby the exploded powder charge.vv

The shell 6 may be provided with a primer 5 of ordinary orany preferred construction.

The cup 3 is preferably of metal such as copper, brass7 gilding, tin, cupro-nickel, steel or iron, or any other metal which may be suitable for this purpose. The sheet metal cup 3 may be formed in any desired manner to have cylindrical walls gradually tapering in cross-section toward the bottom of the shell.

With the use of my improved cup 3 a means is provided for uniformly controlling barrel pressures and velocities, which is necessary'to insure proper functioning of automatic or semiautomatic firearms. This improvement isequally applicable to automatic, repeater, double barrel or single barrel firearms.

The cup 3 is propelled through the bar rel of the firearm immediately behind the shot container, thus preventingthe latter from becoming torn, distorted or ruptured by the gases created vby the explosion of the powder charge, and insures uniform and perfect functioning. As soon as the shot leaves the muzzle ofthe firearm it is released from the protection of the gun barrel and the covering l breaks, permitting 'the shot to spread but slightly. The cup 3 immediately breaks up upon leaving the-gun barrel. Y

The cup- 3 will be held substantially intact until it reaches the end of the gun ,barrel when the force of Vthe explosion will tear it to pieces since it is no longer protected .by the gun barrel. The covering on the shot is also torn as soon asthecharge leaves the gun barrel for the saine reason. The shell 2 in ay be .indented circumferentially at'7 to more securely hold the covering orshot container l inthe open end of the shell with a large portion of thecontainer l projecting from the shell. The container l is therefore in the shape of an elongated. cup with a semi-spherical Y closed end, as shown in Fig. A; The shot charge may vary "according to the length `of the elongated cup l. The wad 2 holds Ythe shot charge inplace in the elongated Ycup conf tainer. yAlter the container is inserted into theopenend or' the shell, as Ashown inlfig.
